    Keller LEO5 Digital Manometer (100bar)

    The Keller LEO5 Digital Manometer is capable of measuring absolute pressure from 0bar to 100bar with accuracy of ±0.05% FS and a resolution of 20mbar via a G ¼” male pressure connector and piezoresistive transducer. There is an additional temperature measurement range of 0˚C to 50˚C with ±1˚C accuracy.

    The clear digital screen on the Keller LEO5 clearly displays pressure and temperature readings and the pressure gauge also produces an analogue signal with a 4…20mA current or 0…10V voltage. The peak capture mode records the highest reading in a measurement period and takes measurements at a rate of 5000Hz as opposed to the 2Hz rate in standard mode. It also boasts min/max recording and zero values.

    The Keller LEO5 has internal memory with enough room for up to 56,000 readings, all with time stamps, temperature readings, pressure and peak pressure. It has a USB port which can be used to download results to a PC and configure the pressure gauge.

    The stainless steel design of the Keller LEO5 – coupled with a sealed, toughened glass frontage – gives it a IP66-rated ingress protection. Up to 1600 hours operation is provided by a single charge of the batteries.
